DESCRIPTION OF THE PREFERRED EMBODIMENT

Pillows are disclosed. In the following description, for purposes ofexplanation, numerous specific details are set forth in order to providea thorough understanding of the embodiment of the invention. It isapparent, however, to one skilled in the art that the present inventionmay be practiced without these specific details or with an equivalentarrangement.

With reference to FIGS. 1 to 3, FIG. 1 is a perspective view of anembodiment of a pillow in accordance with the present invention. FIGS. 2and 3 are exploded view and a cross-sectioned view of FIG. 1respectively.

The pillow in accordance with an embodiment of the present inventioncomprises a main body 1 and a cover 2. The main body 1 comprises a lowerpad 11 and an upper pad 12.

The lower pad 11, as shown in FIG. 2, is made of a flexible or anelastic material, and comprises a first cavity 111 and a pair of secondcavities 112. The first cavity 111 is mounted on the center of the lowerpad 11 and may be a longitudinal ellipse, a water-drop or a shieldshape. The two second cavities 112 are oppositely connected to andcommunicated with the first cavity 111. In this embodiment, each secondcavity 112 is latitudinal protruded from the corresponding first cavity111, and may further comprise multiple optional supporting pillars 113mounted inside the second cavity 112.

The upper pad 12 is mounted on the lower pad 11 and comprises a mainhole 121, a pair of air-flowed holes 122 and at least one optionalauxiliary pore 123. The main hole 121 is mounted on the centre of theupper pad 12, vertically corresponds to and communicates with the firstcavity 111 of the lower pad 11. The shape of the main hole 121 may be ashielded-, oval-, or face-liked shape.

The two air-flowed holes 122 are mounted adjacent to the main hole 121,vertically corresponded to and communicates with the second cavities 112of the lower pad 11. The main hole 121 and the air-flowed holes 122 areseparately mounted on the upper pad 12 instead of connecting to eachother such as the first cavity 111 and the second cavities 112, so thatthe upper pad 12 has a better supporting capability. Similarly, as abovementioned, the supporting pillars 113 are also used for better supportsthat withstand between portions of the main hole 121 and the air-flowedhole 122 at a bottom side of the upper pad 12.

The auxiliary pore 123 is located at a place corresponded to the secondcavities 112 for communicating the lower pad 11, which allows a personto insert a pipe of an air instrument for inputting air such as oxygeninto the first cavity 111 and the second cavities 112 to improve theair-flow efficiency.

The upper pad 12 and the lower pad 11 may be two separate pieces stackedor formed as one-piece.

The cover 2 is a breathable fabric, covers the main body 1 to preventdusts entering to the main body 1, and comprises a first opening 21 anda second opening 22. The first opening 21 is used for inserting the mainbody 1 into the cover 2 and might be disposed on a side or a bottom ofthe cover 2. In the present embodiment, the first opening 21 is disposedon the right side of the cover 2 and can be configured with a sealingassembly such as a zipper (not shown in the figures).

The second opening 22 is disposed on the top of the cover 2 andcommunicates with the main hole 121 of the upper pad 12. In this manner,as shown in FIG. 3, at least one air pathway is formed from the secondopening 22 to the first cavity 111 through the main hole 121. Therefore,a person with the face down position is able to keep smoothly breathingwhile sleeping. In the present embodiment, the second opening 22 is aninversed T-form shape that has a shorter cut at an upper end and alonger cut at a lower end. The shorter and the longer cut respectivelycorrespond to the bridge of the nose and the mouth. However, the secondopening 22 also might be a triangle or 1-form for the nose and mouthpassing through to keep breathing.

In addition as shown in FIG. 3, an upper portion of the main hole 121 islarger than a lower portion of the main hole 121. In other words, acaliber of the main hole 121 is gradually (i.e., upper to lower)diminished to provide a better support as a person laid on the main body1.

Moreover, the cover 22 could be comprised a pair of third openings 23and a pair of fourth openings 24, which are mounted on the top of thecover 2 that adjacent to the second opening 22. The two third openings23 are corresponded to the air-flowed hole 122, which enhance theefficiency of the air transaction above mentioned. In one embodiment,each fourth opening 24 is mounted between the second 22 and the thirdopenings 23 and may apply a pipe or an air instrument inside the pillowto generate and increase the air-flow.

While a person sleeping in a face down position, the second opening 22is slight opened due to the press from the head. The hollowed main hole121 supports the edge around the face instead of pressing the nose andthe mouth to prevent the disruption of breathing. Moreover, because thefirst cavity 111 is communicates with the second cavities 112, theexhaled gas (i.e., carbon dioxide) will be flowed down from the secondopening 22 into the main hole 121 and the first cavity 111, then beintroduced to the second cavities 112, and finally be released out fromthe air-flowed holes 122. Fresh air of the pillow can enter to thepillow in a reverse direction to keep air transaction inside the pillow.

With reference to FIG. 4, FIG. 4 is a perspective view of a pillow, inaccordance with another embodiment of the present invention. In thisembodiment, an additional supporting pad 3 is added, which is disposedadjacent to the pillow shown in FIG. 1. The supporting pad 3 has aninclined surface, a higher side 31 and a lower side 32. The higher side31 is connected to the main body 1 and has same height as the main body1. The inclined surface has multiple parallel grooves 311 that aredisposed at the higher side 31. Two ends of the grooves 311 respectivelyhave a spherical concave 312. While a person sleeps in the face downposition, the shoulders and the chest is able to against to thespherical concave 312 and the grooves respectively. Accordingly, theperson is able to lie down on the pillow from the head to the chest inposition conformity with the ergonomics.

With reference with FIGS. 5 to 6, FIG. 5 is a perspective view of apillow, in accordance with yet another embodiment of the presentinvention. FIG. 6 is a cross-sectioned view of the pillow of FIG. 5. Inthis embodiment, an auxiliary pad 4 is disposed under the lower pad 11.The auxiliary pad 4 can increase a total height of the pillow based on aperson's desired. Further, as shown in FIG. 5, the second cavity 112′shapes can be also like a pair of cow horns. Each second cavity 112′ isprotruded from the first cavity 111 with a noticeable slant.

With reference with FIG. 7, FIG. 7 is a perspective view of a pillow, inaccordance with still yet another embodiment of the present invention.In this embodiment, a bracing plate 5 is disposed between the lower pad11 and the upper pad 12 to provide better support of the pillow. Thebracing plate 5 may be made from a netty fabric or some other similarnet structures.

In order to avoid a difficulty of cleaning when dusts attached to thenet structure and a displeasing appearance that a person may be able toglance the net structure from the holes (i.e., the main hole 121 and theair-flowed holes 122) of the upper pad 12. The bracing plate 5 mayfurther comprise multiple openings 51. Each opening can have differentsize or shapes corresponding to the holes of the upper pad 12. It isnoted that since the bracing plate 5 is buried under the upper pad 12,it will not be seen by a person for providing a better appearance of thepillow.
